LUBRICA'IOR' Be it known that 1, Queen W, DooLrrcrLn', a citizen of the United States, residing at Glenside, county of Montgomery, and State of Pennsylvania, have invented a certain new and useful Improvement in Lubrica tors, whereof the following is a specification, reference being had to the accompany ing drawing.

The invention herein claimed is an im provernent in lubricators of the class claimed in Letters Patent of the United States No. 1,221,295, granted to me April 3, 1917, designed to use dry graphite and including in the lubricant passageway a body adapted to be reciprocated by fluctuations in fluid pressure upon respectively opposite sides thereof. In said Letters Patent, I showed a form of the invention wherein the lubricator structure has but a single outlet for connection with the device which is to be lubricated. However, my present in f vent1on resembles the lubricator claimed in my copending application Serial No. 218,422 filed February 21, 1918, forv etters Patent of the United States, in thatit has a T fitting with two opposite discharge openings from the lubricator; so that the latter may be directly included in an indicator, line on a double acting engine cylinder and in communication with the opposite ends thereof, to supply lubricant alternately thereto. However, in the form of ;my invention shownin said application, the T fitting conthe indicator. Therefore, itis an object and effect of my present inventlon to provide a permanent indicator line with a T fitting andappurtenances adapted to interchangeablycooperate with a lubricator and with an indicator so that communication maybe I of which may bevaried by the screw valve 11, which may be set with its reduced inner end obstructing said port 10 more or less, and be securely held by the jam nut 12 established through the T fitting from the lubricator or indicator to'either endot the cylinder to the exclusion oi": the other end.

As hereinafter described; mypresent invention may include a rotaryplug valve with a transverse passageway in which the.

reciprocatorylbody is mounted in cooperative relation with stationary abutments "for said body having respective passageways through which the lubricant is discharged to Specification of Letters Patent.

big; 1V is a sectional view, in the same plane as Fig. ill, but showing a modified form of l fitting, and with said receptacle in full lines. I i

ln the form of my invention shown in Figspl to I'll inclusive; the casing 1, which is the lubricant supply receptacle, includes the chamber 2 for lubricant, having the screw-threaded lubricant inlet 3 at the top thereot; with the removable closure l whereby said inlet 3 may be manually sealed, and said closure has the duct 5, through which communication may be established' with the atmosphere without entirely unscrewing said'closure. Said closure may be conveniently rotated by means of "the handle 4, preferably formed of some inaterlal whichis nonconductive of heat, but

' said closureis also conveniently provided with the wrench hold 8.

Said casing'l has at its lower end the vertical passageway 10' which is the lubricant discharge outlet port, the effective area Patented Au: 3, 13 20.- Applicatioh filed October 8', 1918. Serial No. 257,345. I

which bears uponsthe lubricant casing l.

Said port 10 extends from the lubricantrenormally rigidly connected with said casing 1. Said body 16 has the port 17 registering with said port 10 and leading to the conical valve chamber 18 for the conical valve plug 19 which is rotary on a horn the plunger valve chamber 22 which extends transversely in said rotary valve plug 19, and has the steel abutments 25 at the opposite ends thereof, to limit the reciprocatory movement of the spherical plunger body 26; which is reciprocated by fluctuations in fluid pressure alternately upon re spectively opposite sides thereof in the indicator pipe line 28 upon the double acting engine 29, indicated in Fig- I, whichineludes the piston 30,the reciprocation of which causes such fluctuations. Such reciprocation. of said body 26 alternately ejects the lubricant through the central ports 27 in the respective abutments 25, which are conically countersunk at their inner endsto facilitate the ejection of the lubricant by said body 26. i As said abut ments 25 are subjected to the hammer blows of said reciprocatory body 26; they are preferably provided with screw threads to secure them in said plug 19 and have means to prevent them from being accidentally unscrewed, conveniently the pins 31'which extend in said valve plug 19 in tangential engagement with said abutments 25," but may be readily driven out when it is desired to remove said abutments; the latter being provided with slots 32 for engagement with a screw driver.

hen in position to dispense lubricant alternately to the opposite ends of said engine 29; said valve plug 19 has its radial port 21 registering with said port 1? and withits diametrically opposite radial ports 27, leading through said abutments 25, in

registry with the ports 34: in said T body, 16,'which open into the respective branches of said pipe 28.

The form of my invention in Fig. IV differs from that above described only in that the rotary valve plug does not carry the abutments which. limit the movement of the reciprocatory body by which the lubricant is forwarded to theopposite ends of the engine 29. In said figure; the T body 36has the upwardly extending branch 37. adapted for connection with the lubricant casing 1, and has the port 38 for registry with the port 10 of said casing, like the Tbody 16 shown. in II; but has the conical valve chamber 39' for the conical valve plug 40 which is rotary on a horizontal axis in said chamber 39, and has the radial port 42 leading to the plunger valve chamber 43 which extends transversely in said rotary valve plug aEObu't does not carry the abutments 415 which limit the reciprocatory movement of the spherical plunger body 46. Said abutments 45 are conven iently screws, slotted to receive a screw driver by which theyymay be lnserted and removed," butare normally stationary in said T body 36 in which they arenormally' held: by the. set screws 48. V

In either form of my inventlon above described; it is only necessarytoremove the lubricator casing 1 from the T fitting, 16 i spective. T. fittings, to establish communication from the indicator to either end of the cylinder, of the engine 29, to thetex-- clusion of the other end.

Although I have shown improved lubricator as provided with two outlets, for

adaptation to the embodiment indicated in Fig. I; it is obvious that if one end ofthe respective valve chambers 22 and 13 were closed theplunger valves 26 and 1-6 would stillbe operativeto dischargelubricant in the opposite direction, as the result of fluctuations ofpressure and consequent reciprocation of-said bodies .26 and 16.

1 Therefore, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications maybe made therein without departing from the essential features of my invention as delined in theappended claims.

I claim:

1. In a lubricator,the combination with a receptacle for lubricant having a screw threaded outlet at the bottom thereof; of a valve body having a'vertical tubular branch.

fitted to said outlet, and two horizontally op- I posite tubular discharge branches; a conical valve chamberin said body, connected by a vertical port opening from. said receptacle; means adjustable to vary the effective area of said port, including a screw extending transversely in said verticalbranch, having its inner end adapted to obstruct said port more or less in accordance with the axial adjustment of said screw; means arranged to hold said screw in adjusted posi- Y tion; a rotary conical plug valve in said chamber, having a port extending radially.
